Voyager (library program)

Modules

The modules are the main way that library workers interact with the system. Voyager is broken down into different modules that are focused on helping with certain tasks commonly done in a library. They are implemented as custom Microsoft Windows programs that talk to a centralized server and database.

The modules are as follows:

The Circulation module takes care of checkin/checkout of books.

Media Scheduling lets people reserve videos and media equipment ahead of time. This usually means a teacher wanting to show a video in class.

Web Voyage lets people search the library catalog using a normal web browser.

Access Reports is a Microsoft Access frontend that lets library workers poke around in the database.

Cataloging helps catalogers work with information about the books as stored in the database.

There are other modules dealing with system administration.

Internals

Voyager uses Oracle as its database. For the web server side of things, it uses Apache. For certain aspects of its reporting, it uses Perl scripts. As stated above, for its modules it uses custom Microsoft Windows programs.

There is no programming API to Voyager as such. There is some documentation about the server-side generation of reports. However, only someone with access to the server would be able to use this information.

For ordinary workers, the only window into Voyager is via the exposed tables of the Voyager database. The Access Reports frontend to this database provides dozens of pre-built SQL queries written by Endeavor to help library workers. It is also possible to write software that connects directly to the database and reads the tables from there. However none of the indexing that makes Web Voyager so fast is exposed for the ordinary programmer.

The tables of Voyager are short-hand versions of the MARC records of the books. The actual MARC is stored as BLOBs but certain portions of the MARC are actual tables. For example, BIB_TEXT.TITLE is, naturally, the MARC Bibliographic Record field that holds the Title. The Bibliographic Records live in tables named BIB*. The Holdings records are in tables named MFHD* (Marc Format for Holdings Data). The Authority Records are in AUTH.

Voyager adds its own record, called the 'Item Record'. This stores the barcode, 'media type', location, and other information. The result of this is that there can be some redundant pieces of information in the database, particularly 'location' and 'media type'.

Support

Ex Libris maintains an Endeavor user support website with links to a mailing list, user-submitted files, manuals, etc. You must have a password to access this website.

There are 'user groups' and meetings of the people who use Voyager. The biggest user is the Library of Congress but many universities, museums, and community colleges also use Voyager.
